Welcome to the Dell E MC unity XT crew removal and replacement series.
In this series of short videos, we're gonna use Unisphere and UEM cli commands to identify faulted custom replaceable units on a Dell E MC unity XT storage system. We'll then look at the ways to prepare the system for service, including service mode and reset and hold modes will demonstrate the removal and replacement of the faulted crew and finally verify the replacement crew is working correctly. One of the first things you want to do is to log on to the storage system using the Unisphere interface. This requires that you have initialized the system and provided an IP address in your browser.
And once you do that, you're gonna be brought to the page that you see here, you're gonna have to have a user name along with a password. That combination was uh also set up during the initialization process. And once you provide those correct credentials, we'll be able to log in and view the dashboard page from the dashboard view. You can see we have a, a critical error as evidenced by the uh red circle with the X. And if we mouse over that, we could see some possibilities as to what that may be. We don't know uh quite yet. And you can get similar information by clicking on the uh view system status icon.
Now, let's take a look at the alerts and the alerts are gonna show us uh some uh possibilities. Here, we see, we have a system error, it's critical error. And if you click on that error, uh you're gonna see that you have some um information in the right hand side about that. You see, it just calls out the uh the array uh as the error here. So let's look at the logs and you always wanna make uh look at the logs, make sure the date and time of that event is logged uh at the same time. And we can see we have a critical error uh called out by the system. But if you look below that, uh we can also see that we have a uh one of the following uh uh errors here. And it's a disc and happens to call out disc uh 18 in the disc processor enclosure.
So we're gonna go ahead and look at the system view. And uh again, we see we have critical errors. Uh I have a ad pe drive 18 that's shown has faulted and I can click on that drive and then click on the blue text and, and visually see uh from the gooey uh and validate that. And yes, the drive 18 is faulted here clicking on that just confirms that and you will have a uh name or led on that drive for, for visibility. If you looked at the uh commands for the drive, you'll see the uh env dis show command, show you that uh you in fact have a fault. So we're gonna replace it. You do that by pressing the orange uh tab down and you're gonna lift that lever and pull it straight out.
Now you want to wait at least 30 seconds before you do that uh Because there's still gonna be some talk on that drive. No, don't. And uh I wanna wait for that to uh uh spin down. Take the new drive uh line it properly into the slot, press it in all the way and then use your lever to press on down. You'll hear that snap in the place and then uh your drive led should come uh online and it will be green at that time, then simply go to the system view and validate that you have fixed the uh crew. And uh we'll see in this case we go to the alerts, the alert was cleared because we had a critical alert and uh uni automatically will clear though when the uh problem was fixed.
And you can see that drive has been uh normally uh in normal condition is operating. Normally, if we can go to the disc uh show command again. In this particular instance, I'm using the id of that disc drive. You see it here as D pe disc 18 and it looks good too. Here we go to the system view. System view shows us everything is green and the enclosure shows us that the part is, in fact uh operating normally and there's no errors. So you have replaced a 2.5 inch drive in a disk processor enclosure.
